FernGreenList ver. 2.0: An Updated Checklist of Wild Fern and Lycophyte Species in Japan

GreenList is lists of names of Japanese wild plants primarily intended for use on the national Red List. The previous version of a list of ferns and lycophytes (FernGreenList ver. 1.01; Ebihara et al., 2017) is available as a part of supplementary data of the study by Ebihara & Nitta (2019) at https://doi.org/10.5061/dryad.4362p32. Since the publication of the previous version six years ago, the number of species to be added to the list has gradually increased. In addition, accelerated publication activities of taxonomic revision in a global scale have resulted in changes to scientific names of Japanese species. Therefore, we compiled an updated version of the FernGreenList.
